.DOUGH SPACER. A*

Application filed December 19, 1924.` -Seria1'No. 756,976.

To all whom t may concern:

Be it known that I, OLIVER W. CoMsTocK, a citizen of the United States, and a resident of Valley Stream, in the county of Nassau and State Vof New York, have invented a new and Improved Dough Spacer, of which the following is Va full, clear, and exact description. a

This invention relates to machinery used in bakeries and particularly toan improved construction known as a dough spacer adapted to receive the dough as it comes from the divider and deposit thesame at spaced intervals on the traveling belt. f

g The object of the `invention is to provide an 4.improved l construction wherein the dough may be readily f received and discharged at spaced intervals andV may bereceived at the next operation at timed intervals thereby eliminating what is known as doubles Y y Another objectof the invention is to pro,- vide a spacer wherein the dough is yfed into the spacer almost `continuously .and is discharged therefrom at spaced intervals in such a manner'as to be deposited a predetermined distance apartv on adjacent traveling belt. N l A n A further object of the invention is to provide a dough spacer for depositing at spaced intervals dough on a traveling belt, Vthe spacer being. such that it is connected up andtimed with the .dough supplying machinery associated therewith. In the accompanying drawings-4 t Figure 1 is a front view of` a dough spacer disclosing an embodiment of they invention, the same being'shown in 'a raised position. Y .A l

. IFigure 2 is a view similar to Figure 1 but showing the parts 4in av lowered position witha quantity of dough ready to be moved.

Referring to the accompanying drawings to contain doughin a certain stage fofpreparation. The hopper 1 is `adapted to feed to the cylinder 2 batches or small quantities of dough from time to time as the cylinder 2 is rovidedwith a central passage-way 3 inw ich .a:.,plyunger Alispositioned.f Suitable mechanism, not shown, is adapted to move the cylinder l2l so that the passage-Way. 3 willV be in line with the hopper l. When this occurs the plunger 4 will be retracted a certain distanceand dough will `be removed by gravity or be forced into the passagef way 3 until thesame is filled from the plungerto the periphery. The cylinder then turns until the passage-way 3 is in a horizontal position as .Y shown` in: Figure `3 and the plunger 4 is causedto function for forcing the dough fromthe" passageway-3.

The structure justdescribed is old andwell nowln, and therefore, has not been shownin etai f Y `The yinvention consistsin an improved structure for receiving the dough from the passageway `3 and discharging` the same onto `a belt V5y which travels at a certain speed in vfrontotthe spacer structure. It will b e understood that there'are alarge number of the` passage-ways .3 in the cylinder 2, there being six in the cylinder 2 asA il- -lustrated in the drawing so that small quantitieswof'dough Vmay be `forced through the .various openings 77p in thespacer., As the cylinder 2` rotates the batches of dough are. forcedcthrough the opening 7 onto the inclinedl platform 8, which lplatforrnuis divided by a number ofdivision walls 9 so that the variousbatchesfor small quantities lOwillbe maintained separate. As soon as the dough has been dischargedthe various ejecting blades 11V are forced downwardly from the position shown in Figure 3 or allowed to move downwardly under the action of `gravity until the parts yassume the position shown in Figure t4. When 4this occurs, the cylinder 2 begins a ,further movement so as to receive another supply of dough4 which will be discharged a little later ontothe inclined platform 8. It will be noted that each of the ejectingl blades 11 is-sharpened at the lower edge and scrapes `.across the cylinder adjacent the various passage-ways 3k so-that they will clean these edges toa certain extent and at the same timel readily pass back of thebatches 10. Flach of the blades 111 isloosely mounted ,on theshaft, 12. Preferably asleeve 13 surroundsshaft l12 'for eachfof the blades 11. Each of the sleeves13' is: provided with a luglor projection 14e, acting" in a certain senseas a `cam and co-acting' with oneof the cams or arms 15` rigidly secured to the shaft 16. :Preferably all of the arms 1Q the position sho-wn in Figure i andthon tho action'- is repeated, 1t will noted that :f eachofthe. arms i is provided with an encircling collar 17 v'pi-ovided with ears through- Whicli bolts 18 ass whereby the collars may be readily adjusted to vary the position ofthearms 15 as may be desired;- the parts have assumed theposi# tion'sho-nia` in Figures 1 and 3, the various Yphiiigggois 4 torto thoV various batons-s 10 SlII-Itlie'Sl-y *Oil-dr the Gliv'd Stllfe 8 and then the cylinder and associatedI parts move back to Vbe refilled While the blades 11'dro'pdown to the position `shown Fig'` ure 4. i Theblades 11 are then' operated in siiooossioii for' 'sao-oossivoly" footingl tlioevaf rionsbatehes' quantities'ofvdouglrv 1() onto the belt 5, ,thel flast baten or quantity l() liasben oioed onto thfblt 5,- the paritsagain assume the position' shown inliiguifoaand the att-.ion ifs repeated-as long' 'as the machine is in operation, j In order toV move the shaft 116i and cause l,'Jlie partsvto assume the position shown iirFig` u-Ies'l and 3, power'v is secured from suitable source, las" for' instance, the mach-ine of which drum ais al part, said power hoingf transmitted throi'igli the elfiain 19 Wherehy tho blades-'i1 Vand otherv patto forming the spacer Will operatedin time rela-tion'- 'slripfwith the drum 2' and assooiated Thrclra'in 19 operates the'v 'sprocket Wheel- 2O xviii-oh is oonnootod to' tho sli-ait` lo through a suitable clutoh, tho saine losing-shown iii Figur'ef Aand illustrated v`as a spring' pressed patvl '21 oo-aoting with a lstop or 221 'By thisl oonstinietionl and arrangement, lif

A bracing rod 27 ist con'- nected to ythe-upper end: of the :racks 24 While the rod 12 is connected to lthe* racks about .midway of their length so that the .various blades llnmay be swingably mounted thereon. Itwill, therefore, be noted that asgthe'sprocket Wheel 20 is rotated, the racks 24 Will be raised and will thereby raise the blades 11 andasso'ciated parts but will au* tomatically release the same as the respective segmental gears move'away from theV racks.- TliisWil'llalloW the'blades lland associated partswtodrop down under` the action of ygravity to substantially the position shown inV Figure y4, after which, rthe blades are actuated by the various arms'l.
